i  want to ask questions :

1 ques .. the current gain of a transistor is 50 . the input resistance of the transistor , when used in the common emitter configuration ,is 1kohmn . the peak value of the collector a.c . current for an alternating peak input voltage 0.01 v is ?? 

2 ques ..in a n-p-n transistor circuit , the collector current is 10mA . if 90% of the electrons emitted reach the collector then the emmiter current (IE) AND base current (IB )  ARE given by:??? 

 

3 QUES.. the minimum potential difference between the base and emmitter required to switch a sillicon transistor "on" i approximately:??

4 ques.   in common emitter transistor , collector  supply voltage is 15 v  if current gain = 100  , base current is 5 uA and collector resistance is 5 k ohm then voltage across collector emitter is :???

 

5 ques .. a zener diode connected across a source voltage of 12v such that 6 v drops across it . the power drawn by zener diode is 2.4 mw , then what is the maximum value of series resistance connected in the circuit ???
